The headers are usually empty, containing no data and not even the -proper header for the claimed protocol. The three exceptions are TCP, -UDP, and ICMP. A proper protocol header for those is included since +proper header for the claimed protocol. The exceptions are TCP, +UDP, ICMP, SCTP, and IGMP. A proper protocol header for those is included since some systems won't send them otherwise and because Nmap already has functions to create them. Instead of watching for ICMP port unreachable messages, protocol scan is on the lookout for ICMP
